Answer:
268
Step-by-step explanation:
We need to multiply and add:
47 tables of 4 means there are a total of 47 * 4 = 188 people at these tables.
16 tables of 5 means there are a total of 16 * 5 = 80 people at these tables.
Add them up to get: 188 + 80 = 268 customers total.
What is f(x) =3x^2-7/4x^2-3 find f(2)
f=5/8x^2+-3/2
Divide both sides by two

does anyone know what -23= 13w+2w+22 is plz help!
Answer:
w = -3
Step-by-step explanation:
-23 = 13w + 2w + 22
Combine like terms (add 13w and 2w and subtract 22 from both sides)
-45 = 15w
Divide both sides by 15
w = -3

How do I solve for the missing angle?!
And please include explanations on how you got the answer
Answer:
75°
Step-by-step explanation:
In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.
In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5
We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105
x is the supplement of 105. 180-105=75
George is 3 years older than the quotient of Joseph's age and 2. Letj represent joseph's age. Write an expression in the box
that would show George's age
Answer:
j/2+3
Step-by-step explanation:
Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.
Then it says that George is 3 years older, so that would be addition.
Therefore, it would be:
x/2+3
The system of inequalities in the graph represents the change in an account, y, depending on the days delinquent, x. On a coordinate plane, 2 dashed straight lines are shown. The first line has a positive slope and goes through (negative 2, negative 2) and (0, 0). Everything to the right of the line is shaded. The second line has a negative slope and goes through (negative 2, 2) and (0, 0). Everything to the left of the line is shaded. Which symbol could be written in both circles in order to represent this system algebraically? y Circle x y Circle –x ≤ ≥

WILL MARK BRAINLEST, HELP W/ MATH QUESTION !!!
Answer:
The average rate of change is 0
Step-by-step explanation:
You don't really have to do any math for this problem. The vertex lies at the center of [-2,11] so it means that the slope going across the interval line (x=1) is 0. (i used desmos to graph it)

A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour? Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.? Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
Answer:
She rode 17.4 miles in 1 hour
Step-by-step explanation:
A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?
The quotient is the average speed and this is calculated as:
Speed = Distance(miles)/Time(hours)
Where speed = quotient
Distance = Dividend
Time = Divisor
Speed = 60.9 miles/3.5 hours
= 17.4 miles/hour
Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
If :
3.5 hours = 60.9 miles
1 hour = x miles
Cross Multiply =
3.5x = 60.9 miles
x = 60.9/3.5
x = 17.4 miles
Hence, she rode 17.4 miles in 1 hour

HELP ME!!! I WILL MARK AS BRAINLY
Answer:
4
Step-by-step explanation:
We can see from the two marked points the coordinates are: (2, 8) and (4, 16)
That means the rise (vertical change) is 16 - 8 = 8 units. And the run (horizontal change) is (4 - 2) = 2 units.
Therefore slope = rise/run = 8/2 = 4.

What type of association is shown by the data in the scatter plot?
Answer Choices:
A. positive association
B. negative association
C. no association
D. trend association
=================================================
Explanation:
We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.
Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.
-----------------
Extra info:
Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points. The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.x^2 + 7x – 18 = 0
a
{–2, 9}
b
{–9, 2}
c
{2, 9}
d
{–2, –9}
Answer:
b)-9,2
Step-by-step explanation:
x^2+7x-18=0
x^2+9x-2x-18=0
x(x+9)-2(x+9)=0
(x+9)(x-2)=0
therefore
x=-9
x=2

If a rectangular prism has a base area of 14 square centimeters and a height of eight centimeters, what is the volume?
Answer:
The volume is 112 cm³
Step-by-step explanation:
I think it's 112 because to find the volume of a rectangular prism you must multiply the length* width* height and 14 the base( base =legth*width) multiplied by 8 equals 112 cm³

Find V. 10 points plz.
Answer:
v = 60 yards
Step-by-step explanation:
In the similar triangles, their corresponding sides are proportional which means they have equal ratios
In triangles IHG and FHJ
∵ Δ IHG ≈ FHJ
∵ Side IH is corresponding to side FH
∵ Side HG is corresponding to side HJ
∵ Side IG is corresponding to side FJ
→ Their ratios are equal
∴ [tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]
∵ IH = 54 yards and FH = 72 yards
∵ IG = v and FJ = 80 yards
→ Substitute them in the first and last ratios above
∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]
→ By using cross multiplication
∴ v × 72 = 80 × 54
∴ 72v = 4320
→ Divide both sides by 72
∴ v = 60 yards
